Face ID Problem?

Hi,

• Your iPhone’s temperature is too hot and needs to cool down.
• I would turn it off by following the instructions here: https://support.apple.com/guide/iphone/iph841379c3d/ios then leaving it for 15-30 minutes or so, this way it can cool down quicker.
• If the message is still showing, the ambient temperature may be too high or the iPhone may have a hardware issue that should be looked at by Apple at an Apple store or authorized service provider.

Looks like your iPhone is overheating. Click on the Get Support link at the top right of this page to start the service process.
